Student injured in San Ramon senior prank

One student was injured in a San Ramon high school senior prank on Friday that the principal said disrupted “an entire school day” and required police attention.

Seniors at California High School jammed locks with toothpicks, sprayed water and Silly String, threw water balloons in the cafeteria and ditched their fifth period classes to storm the pool complex, with some actually jumping into the water, according to an e-mail sent from Principal Mark Corti to parents.

During all this, one student was injured and required medical attention, Corti said in the e-mail. He did not say how the student was hurt, or the extent of the injuries.

Corti said he had to call in the district maintenance team, San Ramon police and the San Ramon Swim Center staff for assistance.

“During my 15 years as the principal I have never seen students disrupt an entire school day, willfully defy administrators and a variety of staff members,” he wrote. “Please have a conversation with your student this evening to reinforce the importance of being respectful to their peers, adults, school property and community property.”

While Corti expressed disappointment in his students’ actions, some seniors took to Twitter to express their pride.
